With penny slots, all the player needs to do is enter their money into the machine and hit a button. Enter the money in the machine, select your lines or bet size, hit the button, and hope for the best. There is no thinking or decision-making involved like in blackjack, sports betting, poker, and so on.

A player may bet on single numbers, rows of numbers, or on adjacent numbers. A player also may play colors, odd or even numbers, among others. A bet on a single number pays 35 to 1, including the 0 and 00.
